I'm hoping this is an example Poe's Law.
First, Texas is not a "right to work" state. In Texas, an employee can be fired immediately for anything at the employer's whim of the moment except the specific classifications identified in the Civil Rights Act...which does not protect political activities, btw.
Second, employers have
always fired employees who acted outside the best public interest of the company. Fifty years ago, an employee that embarrassed the public image of his employer got fired, just like today.
And have you ever seen the rules laid down for a schoolteacher a hundred years ago?
